Twenty-eight preschoolers and two adults mistakenly drank bleach at snack time at a New Jersey day care center on Thursday and were taken to a hospital after some complained their stomachs were burning.

The children, aged 3 and 4, and Nike Air Max UK staff members of the Growing Tree Learning Center in downtown Jersey City were transported in five ambulances to the Jersey City Medical Center after a late-morning call to 911, said Mark Rabson, a hospital spokesman. He said some complained of light-headedness, others of upset stomachs.

By mid afternoon, all 30 were in stable condition and were being discharged, Rabson said.

"There was a poisoning and many children were injured," he said, adding the children were walking on Nike Air Max Sale own or were being carried out by their parents and "have smiles on their faces."

Keith Kearney, executive director of United Cerebral Palsy of Hudson County, which runs the day care center that is open to all community members and serves 65 children from infants to age 4, said he had heard no reports of injuries and that the hospital visits were a precaution.

"We had an incident where one of the Nike Air Trainers in the kitchen used the cleaning solution bottle to pour water for some of the children," Kearney said.

"It was a repurposed plastic milk jug with a bleach water solution we use to wipe down surfaces. The Nike Trainers we had on the bottle wasnít large enough to guard against it," he said.
